> CNBC > Commodities Bubble Burst? Big Clue Comes Next Week > Monday March 24, 3:19 pm ET > Investors wondering whether the agricultural commodities bubble has burst will get some important clues in next week's annual crop plantings report, considered a bellwether for the direction of farming activity for the year. > Analysts are looking for the Department of Agriculture's March 31 survey to show a decrease in corn acreage over last year's record planting, as well as a pronounced increase in soybeans and more wheat in the ground. > But what those projections will mean for investors remains to be seen. Commodity analysts are expecting volatile planting numbers this year, with the weather and direction from traders to play a major role. > Wet conditions in the heartland, for instance, could depress the amount of corn acreage, raising its price in turn. Soybeans, meanwhile, likely will get more attention this year after losing acreage to corn in 2007 due to a sharp increase in demand for ethanol. Wheat also will be in flux, its price subject to possibly lower demand due to resumption of planting worldwide after a year of a supply-constricting global drought. > How the three major agricultural products fare is of major concern as investors wonder whether the commodity's bullish run of record- setting prices will continue or has run its course. > Run for Oil, Gold at Its End? > Other commodities, such as gold, platinum and oil also have seen record runs, but there is sentiment that the end may be near. The commodities run has been fueled by speculators and those cashing in on the weak dollar, the currency in which most commodities are traded. > "Planting intentions are very important to how our supply and demand balances will look this coming year," said Melvin Brees, an agricultural economist at the University of Missouri's Food and Agricultural Policy Research Institute. "One of a number of factors is the unpredictability of the weather." > Corn takes the biggest hit from bad weather, as it needs to be planted the earliest of the other major crops. It also does not plant well in saturated soil and requires the most fertilizer, which has become more expensive as the United States has lost its place as the world's primary manufacturer. > Continued rainy conditions, or an excessively wet spring, could alter the agricultural commodities market dramatically, sending corn prices well higher on less supply. > "That would create a huge amount of volatility in the markets," Brees said. "With supplies as they are, you would probably see a sharp market reaction." > Despite a record corn planting last year, there was only a slight increase in carryover â" the amount that's left over from the previous harvest â" to the spring. Should corn production drop this year, that could make supplies very tight and become a bullish indicator for prices. The same thing goes for wheat and soybeans, both of which also saw low carryover rates, attributable to surging demand from emerging markets across the world. >
